Product description

The parallel, smooth jaws automatically grip hexagonal bolts and nuts, thereby preventing damage or the edges becoming rounded. The integrated lever mechanism ensures a secure grip and significantly reduces the risk of slipping. Thanks to the ratchet mechanism, work can be carried out without putting the tool down, enabling bolting tasks to be completed much more quickly.

The swivel angle of just 30° allows for comfortable working even in confined spaces. In addition, the practical hanging hole ensures easy and tidy storage in the workshop. The Wera Joker 6004 is available in four versions and covers both metric and imperial screw sizes.
